Answer:
25/36 cm^3
0.69444... g/cm^3
Step-by-step explanation:
Find volume of cube: 4*12*3
144 cm^3
Rember the density formula: g/cm^3
subsitute:
100g/144cm^3
simplified 24/36 cm^3
0.69444... g/cm^3
Answer:
First to find AB we use cosine
cos ∅ = Adjacent / hypotenuse
AB is the adjacent
BC is the hypotenuse
cos ∅ = AB/AC
cos 70 = AB / 8
AB = 8 cos 70°
AB = 2.736
AB = 2.7cm to one decimal place

The discriminant of the function is 120, and the function has 2 different x-intercepts
<h3>How to determine the discriminant?</h3>
The function is given as:
f(x) = -7x^2 + 8x + 2
The discriminant (d) is calculated using:
D =b^2 - 4ac
So, we have:
D = 8^2 - 4 * (-7) * 2
Evaluate
D = 120
Because the value of D is greater than 0, then the function has 2 different x-intercepts
